Having irreplaceable batteries makes your device have a very short lifespan. This is horrible for the environment. I'm typing this on a pixel 1 that I've replaced the battery in, and have used for 4+ years.

Laptops should have replaceable batteries. Period. If you get a new laptop every 2 years and don't know what it's like to have a perfectly good MacBook with 30minutes of battery life, then maybe you can just imagine being in that position and consider how globally impactful this anti consumer practice is.
